2.2 Unpacking the controller software

Do the following to prepare the downloaded HP VAN SDN Controller software package for installation:

1.Ensure that you have root access on the Ubuntu system (sudo).

2.Unpack the HP VAN SDN Controller from the directory in which the package is stored:

NOTE: In the following command, two hyphens precede the unpack keyword; that is, --unpack.

~$ sudo dpkg -–unpack hp-sdn-ctl_2.4.x.yyyy_amd64.deb (Where x.yyyy completes the actual release version number of the controller. For example, 2.4.3.0595.)

2.3 Installing and verifying the controller

To install the downloaded HP VAN SDN Controller software:

1.Execute the following command to install software dependencies and complete the installation: sudo apt-get install -f

2.Verify the controller installation:

~$ sudo dpkg -l hp-sdn-ctl

If the HP VAN SDN Controller package is properly installed, output similar to the following appears:

ii hp-sdn-ctl

2.4.3.0595

HP VAN SDN Controller

NOTE: The ii in the above output line indicates a successful controller installation. Any other characters appearing instead of ii (such as iU) indicates that the controller is not correctly installed. In this case, see “Troubleshooting” (page 21).

3.Use the following command to start the controller, then wait 60 seconds before proceeding: sudo service sdnc start

Wait 60 seconds to allow for the sdnc service startup to complete.

4.In the command line window, verify that the sdnc service is started:

~$ sudo service sdnc status

You should see the following output, which indicates that the sdnc service is started:

~$ sudo sdnc start/running, process nnnn

VAN SDN Controller Software Products specifications

HP VAN SDN Controller Software Products represent a significant advancement in network management by leveraging software-defined networking (SDN) principles. These products aim to centralize control of network resources, provide enhanced automation, and simplify network management, which can dramatically improve the overall performance and agility of data centers.

One of the main features of HP VAN SDN Controller is its ability to enable an application-centric network environment. By separating the control plane from the data plane, network administrators can gain a holistic view of the entire network. This separation allows for dynamic reconfiguration of network devices and sets the stage for the development of innovative applications that can respond to real-time network conditions.

The controller supports OpenFlow as its primary protocol, ensuring interoperability with a wide range of network devices from different vendors. This compatibility facilitates a heterogeneous network environment, allowing organizations to transition to SDN at their own pace without needing to replace all existing hardware. It also promotes vendor diversity, reducing the risk of vendor lock-in.

HP VAN SDN Controller features robust security capabilities, including support for micro-segmentation, which helps in isolating critical components within the network. This layer of security can safeguard sensitive data and protect against threats, ensuring that only authorized traffic is allowed within designated network segments.

Another key characteristic is the controller's emphasis on automation and orchestration. Through APIs and built-in tools, network policies can be defined and applied consistently across the entire network. This intelligent automation reduces the potential for human error and accelerates the implementation of networking changes, enabling organizations to adapt quickly to evolving business needs.

The HP VAN SDN Controller also incorporates advanced analytics capabilities that provide real-time visibility into network performance. These analytics can help in troubleshooting, forecasting capacity needs, and optimizing resource utilization, contributing to improved operational efficiency and reduced downtime.

Furthermore, the scalable architecture of the HP VAN SDN Controller makes it suitable for various environments, from small enterprises to large-scale data centers. The product supports multi-tenancy, allowing multiple virtual networks to coexist on the same infrastructure, which can be ideal for service providers and organizations operating within cloud environments.

In summary, HP VAN SDN Controller Software Products deliver a powerful suite of features and technologies that enhance network control, security, automation, and scalability, positioning organizations to leverage the full potential of software-defined networking.
